简要总结
According to ISO 15197:2013 and EN ISO 15197:2015, at least three reagent system lots of a blood glucose monitoring system have to be tested. For each of these three lots, at least 95% of measurement results have to lie within ±15 mg/dl or ±15% of the results obtained with manufacturer’s reference method for reference results <100 mg/dl or =100 mg/dl, respectively. In addition, at least 99% of results across all three lots have to fall within CEG regions A and B (CEG: Consensus Error Grid). In the primary analysis versus the manufacturer’s reference method (for all systems YSI 2300 STAT Plus, glucose oxidase-based), the following results were found (n = 200 measurement results each): - System A: 100.0% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System B: 95.0% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System C: 96.0% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System D: 87.0% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System E: 95.0% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System F: 66.0% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System G: 89.0% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B In the secondary analysis versus the alternative comparator (for all systems Cobas Integra 400 plus, hexokinase-based), the following results were found (n = 200 measurement results each): - System A: 98.5% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System B: 91.5% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System C: 88.0% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System D: 93.5% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System E: 89.5% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System F: 42.0% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B - System G: 77.5% within ±15 mg/dl or ±15%, 100.0% within CEG regions A and B
